Mine are pellet free so have a huge amount of dried forage in the winter - can't wait til the spring as it costs me a fortune, and I'm hoping to dry enough of my own for next year to not have to buy in! Got them too late this year to start really, though I got some.
They have quite a variety, and it's all fed in different ways. They have a leaf mix (nettle, dandelion, rapsberry) which I mix with dried coriander, dill, lemon balm, green oat, chickweed,readigrass and probably other stuff that I've forgotten and that gets fed in a big wire cube that they love throwing around. They have dried plantain in a small wire ball, or a holey rubber ball. Dried mint in a similar ball. Strawberry leaves sometimes go in the cube and sometimes go in a ball cage feeder that hangs up. Mixed dried fruit leaves are in a rack above one of the litter trays. Dried chamomile flowers in a kind of bowl, or in a toy maze feeder. Various other bits and bobs, dried flowers, random stuff, gets fed in as many different ways as I can think of. Smaller bits are sprinkled on snuffle mats or in snuffle boxes of hay. Dandelion roots hidden around their pen to sniff out.
I find it fascinating to watch them, because I try to make sure they have a huge variety at all times in almost free amounts (within reason), so they can choose what they need alongside lenty of fresh food and obviously hay and grass. There are clear links between the weather and their feeding habits, and they don't always go for the fresh foods or "treat" items such as carrot before they go for dried forage for example, it just depends on how the day has been. Endlessly fascinating to observe how they pick and choose and tallying it to external factors.
This year I want to really make the most of my garden, harvesting the herbs, rose bushes, shrubs and fruit trees to the max so next year they should have even more variety.
